The door opening 11 is adapted to be closed by a sliding door 19 which may be mounted upon the car in any desired manner. The structure of the door and means for mounting it upon the carl are both well known. For the purpose of the instant invention it may be stated that the door embodies a corrugated metallic panel 20, the rear vertical margin of which is reinforced by means of a substantially W-shaped member 21 and a backing plate 22 associated with the metallic panel to provide a substantially tubular construction. The rear edge of the reinforcing member 21 is flanged as indicated at 23 so as to cooperate with a spark strip rivets 26 which extend through the bracket, the metallic panel 20 land av reinforcing member 27 disposed within one of the corrugations of the panel. As shown in Fig. 2 of vthe drawings the bracket follows the contour of the substantially W-shaped door reinforcing member 21. The rear edge of therdoor bracket 25 is provided with a downwardly and inwardly inclined recess 28 formed in part by a rearwardly extending llange 29. The flange 29 is turned outwardly and rearwardly as shown at 30 and is provided with a seal slot 31.

A bracket 32 preferably in the form of a casting is secured to the door post 12 in the co-rner provided by the angularly related flanges 15 and 16 of the door post. The upper portion of the bracket is angular in cross section and embodies an outwardly extending flange 33 and a llange 34 which is parallel to the side wall. tal flange 35 at the top of the bracket which connects angular horizontal flange 35. Below the ilange 35 the bracket 32 embodies a wall 36 which lies parallel to theside wall of the car.. The wall 36 is reinforced by means of an outwardly extending rib 37 which merges into a horizontal flange 38 formed at the bottom of the bracket 32 and connecting rib 37 and outwardly extending llange 33. A pin 39 extends through the upper horizontal llange 35 and thelower horizontal flange 38 to which Q it is secured as by means of welding.

The pin 39 extends through a boss 4l) formed in a locking member 41so as -to support the locking member for Vertical sliding and horizontal swinging movements. The end of the'locking member opposite the boss 40 is inclined similar to the inclined recess formed in the door bracket 25 as indicated at 42. When the member 41 is in locking'engagement with the door bracket 25 the end 42 of the locking member is received tion of rib 37 of the bracket 32. Lug 46 is spaced from flange 16 of the door post as shown in Fig. 3 of the drawings so as to permit the lug 45 of thelocking Y member 41 to be disposed between the-lug 46 and the A ange16. 1

The flange 16 carries a substantially channelshaped member 18 which is secured to the llange A1 6 as Flange 34 extends downwardly froma horizon` A substantially goose-neck shaped member 47 depends from the horizontal flange 38 of the bracket 32. The member 47 is adapted to extend through an eye 48 formed in the upper end of aopeningand closing-.lever 49v which is thereby suspended from the member 47 for swinging movement in atplaneisubstantially. parallel to the side wall and in a plane at an'angle to theside wall; The lever 49 is provided with an elongatediopeningSO` disposed below the eye 48.` A lug 51 depends from the door bracket 25 and is adapted to extend throughrthe eye 50 when it is desired `to impart initial openingend tinal closing: movement to the door. lt will be observed from Fig; l of the drawings that the lug 51 partially overlaps `thelever 49 so as torestrict the outward swinging .f

movement ofthe lever when it' is suspended from the member 47. Also to prevent swingingmovement of the lever 49-parallel to the'side wall when `thelever is suspended lugs 52 `and 53 are provided which lie on oppoL site sides of the lever 49.

`In Fig. 2 of the drawings the door is illustrated in closed and locked position. At this time the end or nose 42 of the locking member 41 is received within the recess 28 of the door bracket A25 so as to prevent movement of the door in opening direction. However, as a result of the inclination of the recess 28 and nose 42 of the locking member and of the fact that the lockingmember is slidable vertically on the pin 39 the locking lever may be lowered by the actionof gravity in the event that the door is not fully closed and moves in closing direction. This` lowering movementof the locking member takes up the slack which is created by the movement of the door in closing direction so as toautomatically re-establish engagementrbetween the locking member and the door bracket. Hence while the door may moverin closing direction if it is not fully closed the noted cooperation `between the lockingmember and the lock bracket prevents movement of the door in opening direction and therefore undesirable lashing ofthe door.

When it is desired to open the door the seal (not shown) which extends through the seal slots 31 and 44 is removed andthe locking member 41'is'moved vertically upward on the pin 39. This movement is continued until thetlug 45 on `the locking member lies above the lug 46 formed on the bracket 32; The locking member 41 is swung inwardly toward the car side andthen lowered on the pin 39 until the lug 45 lies behind the lug 46.v When this relationship between these lugs `is established the locking member is positively retainedin such position that it-will notinterfere either with theopening.. or closing movement of the door.

ln order to impart initiall opening movement to the door the lever 49 is swung outwardly so as to be disengagedfromthe lugs 52 and 53 andlis then engaged'with thelug` 51 by passing the elongatedslot 50 over Athe lug 51. and after this occurs the lever `is disengaged fromr the lug 51 and dropped to its inoperativeposition between the lugs 52 and 53. The door may then be fully opened.

In order to close and lock the door itis first moved across the door opening'll -into substantiallyth'e position'` shown in Fig. 2 of the drawings; Thelockingmember 41` is then raised so as to disengagelug 45 'from 1ug46-` after which it is swung outwardly about theipin 39 and the nose of the locking member is engaged' in the recess of the door bracket. ln this position the Vlocking member is prevented from swinging outwardly by ange 29`and( inwardly by rib 37. If necessary, thelever 49 is engaged with the 1u`g`51 in orderto impart final closing mov`ement to thedoor and lpermittheabove described engagementbetween the locking member and the door` bracket'. After tliis engagement has been established a seal is passed` through the seal slots `31` and44 in order; to seal the `door in closed'position; If-atthis timethe door is. not fully closed it may move in closing direction and-the The door may then be started in op'ening;direction r portingtbrackettsecuredto-said sideiwall, alockingmem 75 ber, Arrteansfrnounting `said lockingjvmemberH on saidjsnp-` slack created by, such movement will be automatically absorbed by the door lock.

It will be apparent that numerous changes and moditications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such changes and modications be comprehended within this invention which is to be limited only by the scope ofthe claims appended hereto.
